Infiltration and Attenuation Systems

The DRAINMAX Tunnel trench can be used for a multitude of applications. To easily achieve this, the system can be extended to almost any size by adding further tunnels or rows.The most important examples for possible system layouts can be seen under:

Save heavy rainfall and infiltrate it in the same location.For the infiltration of rainwater from sealed surfaces, there are a number of different possibilities. INTEWA offers you complete solutions for trench and trough infiltration.

Save heavy rainfall and throttle the runoff, if infiltration into the ground is not possible.Rainwater retention is necessary if the introduction of runoff into the public utility is restricted. Dependent on the restriction, a necessary retention volume is calculated in order to temporarily store heavy rainfall events on th spot. This necessary buffer volume can be stored above ground, as in a basin, or underground.
